FBI agents are reportedly looking into Democratic Sen. Robert Menendez’s dealings with two fugitive Ecuadorean bankers, according to a New York City TV station.

WNBC in New York — citing anonymous sources — reported on Thursday evening that the New Jersey senator contacted the Department of Homeland Security and the State Department on behalf of William and Roberto Isaias Dassum. The brothers are fighting extradition to Ecuador over charges that they allegedly embezzled tens of millions of dollars from the country’s largest bank before it failed and had to be rescued by the Ecuadorean government.

The brothers were convicted in absentia in 2012, but a Florida court refused to allow the Ecuadorean government to seize $20 million in assets the Dassums held in the United States. Ecuador has already confiscated $400 million worth of property owned by the brothers back home, including media companies.

The criminal investigation into Melgen and Menendez has dragged on for more than a year with no charges against either man, but this latest report puts Menendez back into scandal mode.

Menendez’s office criticized the WNBC report as based on anonymous sources, and added that Menendez “was not aware” of any criminal probe into his interactions with the Dassum brothers.

“A year after a false smear campaign was launched against Sen. Menendez, once again we see anonymous sources making outlandish allegations,” said Tricia Enright, a Menendez spokeswoman. “Our office works each year with literally hundreds of individuals and families from across the country who are seeking help with the immigration process. We review each and every request we receive, and if we feel any inquiry is appropriate, we make it.”

Enright added: “In this particular case, Senator Menendez believed the Isaias family had been politically persecuted in Ecuador, including through the confiscation of media outlets they owned which were critical of the government. We are not aware of any inquiry into the senator’s actions on this matter.”
